COLORING- YARN IN THE BOBBIN.

Speccation of Letters Patent No. 17,708, dated June 30, 1857.

T 0 all whom it may concern:

Be it known that we, J AMES THOMSON and WILLIAM P. WAKELEE, of NewHartford, in the county of Oneida and State of New York,

have invented a new and Improved Mode of Dyeing Yarn; and we do herebydeclare that the following is a full and exact description thereof,reference being had to the annexed drawings and to the letters ofreference marked thereon.

The nature of our invention consists in providing the means of dyeingyarn in the cop, or bobbin, without reeling it off into hanks, orskeins, for that purpose, as is usually done. In order to let the dyepass into the mass, and reach all the fibers, and thoroughly color thewhole in a uniform manner, and with great rapidity, we place the yarnwhile in the cop, or bobbin, as it comes from the mule or throttle inspinning, within a tight box or vessel, in such a manner as to receivethe liquid dye to great advantage, and then exhaust the air from theinterior of the vessel. Then by opening certain faucets the dyeingmaterial is let into the vessel, passing through and among the threadand fibers of the yarn in each cop as it enters; thus reaching andthoroughly dyeing the mass in a perfect and uniform manner.

A, B, Figure 1 is a perspective elevation of c, d, e, is the to of thevessel in which the yarn is to be dye it isa large rectangular box,which we denominate a receiver, of which f, g, 7L, is the interior, thefront plate, which is necessary to perfect the inclosure, being takenoff, and is shown separate in Fig. 3. t, c, Z, are specimen cops ofyarn, showing the manner of their being set within the receiver.

Fig. 4, represents a specimen of a hollow skewer or spindle, which isinserted in each cop of yarn preparatory to being placed within thereceiver. These skewers are open at the largest end, a, and closed atthe end b; and they are perforated by numerous holes as shown in thefigure. The cops to be dyed being thus prepared, each with a hollowskewer, they are set into movable plates f, h, (Fig. l), and similarones m, m, immediately over them, the open ends of the skewers standingin the plates. These plates being perforated by ranges of holes toreceive them. The plates are then slid into their places in the receiveron ways fixed to the sides of the box: the cops standing upright in thelower plates, and hanging perpendicularly from the upper ones, as shownby the specimens i, k, Z, i and Z standing in the lower plate, and 7changing from the plate above. Fig. 2, represents a specimen of theseplates with only one range of holes; the number of ranges are of coursegoverned by the dimensions of the plates, or size of the receiver, andthose in the upper and lower plates, match and alternate with eachother, so that the plates may be inserted, and withdrawn separately, theranges of cops in one passing between those of the others. These platesstudded with cops being thus inserted a vacant space o, o, is left belowthe lower plates, and a like space is also left above the upper platesm, m, within the body of the receiver. The door plate A, (Fig. 3) is nowscrewed up in front, and packed to make the oinings perfect, so that thewhole box shall be air tight. The liquid dye to be used is placed in thevats p, and g, (Fig. 1), one of which is to supply one apartment of theengine, and the other one the other apartment, the engine here describedbeing double, each apartment being capable of separate action, thepartition r, being the division between them. Before the coloringmaterial is admitted into the receiver, the air is exhausted therefromas near as may be, by the air pump S, T, which by the usual arrangementis made to connect with its interior. The interior of the receiver beingthus made a vacuum the next step in the process is to let the liquid dyeinto it. For this purpose the cut off faucets a, a, are turned, and theliquid dye rushes through the pipes connected with these faucets intothe spaces 0, 0, at the bottom of the receiver, one of these pipesconnecting with one of the departments of the engine, and the other onewith the other department. From the spaces o, o, it passes up the hollowskewers set in the lower plates, and passing through the numerous holesin these hollow skewers it penetrates the yarn of the cops, fillingevery interstice between its fibers, the air having been discharged fromall these interstices. Thence filling the body of the receiver it in thesame manner passes in the inverse direction through the mass of yarnforming the cops hanging from the upper plates, seeking the vacuumwithin their hollow skewers; and thence into the vacancies m, fm, above.This passage of the liquid is very rapid, being under the pressure ofthe entire Weight of the atmosphere when a perfect vacuum is formed, andsoon fills the entire receiver. From the chambers m, m, there is apassage through the pipes U and V into the receiving cylinders W, and X,Which are at the same time also exhausted of the air through the pi esZ, Z. These cylinders are designed mere y to keep up the liovv of theliquid through the yarn for a longer time on the opposite side ofthemachine; the pi es D, at the same time draining the cylin ers W and X.The door Way in front being then removed the cop plates are drawn out,the cops removed and others put in their places and the same process isre eated.

Fig. 5, represents a cop fuil dyed as When taken from the engine. As t edepartments on the respective sides of the partition 1 are entirelyseparate, various coloring materials may be used at the same time. Themachines or engines may be made single, or they may be duplicated asoften as may be de- I material into the sired, using various kinds ofcoloring at the same time. The engine here represented exhibits themanner of duplicating the machine, While at the same time as thearrangement for each department or division of a double or triplemachine is independent of the others, a single department may be usedWithout using the others. The ipe and faucet F serve merely to draw offt e vapor that may condense and settle at the bottom of the air pump.

We are aware that a vacuum has been used to facilitate the admission ofthe dyeing ores and around the fibers in the dyeing of c oth. We do nottherefore claim the use of a vacuum for the purpose of dyeing generally.But

at We claim as neW, and desire to secure by Letters .Patent is- The useof a vacuum, in combination With our arrangement of ap aratus t0 renderthe same available in the yeing of yarn in the cop, bobbin and the like,Without first reelingV it into hanks or skeins, as described, the

Whole apparatus being constructed and op' erating substantially in themanner and for the purposes herein set forth.
